Running the following query in SQL Server Management Studio gives the error below.
update table_name set is_active = 0 where id = 3
A severe error occurred on the current command. The results, if any, should be discarded.
I have tried the same update statement on a couple of other tables in the database and they work fine.
DBCC CHECKTABLE('table_name');
gives
DBCC results for 'table_name'.
There are 13 rows in 1 pages for object "table_name".
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
I just had the same error, and it was down to a corrupted index. Re-indexing the table fixed the problem.
